WHEEL AND AXLE LATI-iE.

SPECIFICATION forming part of Letters Patent No. 584,846, dated J' une 22, 1897.

Application filed December 1S, 1896. Serial No. 616,182. (No model.)

To @ZZ 1.071.071?, t may concern:

Be it known that I, HARRY CLAUDE Boo- QUET, a subject of the Queen of Great Britain and Ireland, residing at Llanwye, Hampton Park, Hereford, in the county of Hereford, England, have invented a new and useful Improved Small Wheel Lathe, of which the following is a specification.

This invention has reference to an improved small wheel lathe which can be adapted for any gage' of railway ortramway wheels to face tires up to, say, four feet in diameter and to turn and true up outside journals of axles.

The way in which I carry out my invention is as follows: A

On a bed-plate having two ordinary fixed center head-stocks and a pair of compound slide-rests for the operating-tools I arrange two Aeshaped standards, which may be of east-iron. These A-shapedstandards have hinged bearing-caps at the top, which support a hollow cast-steel carrier-shaft of such dimensions as to take the largest diameter of small-wheel axles in use, the bearings of the pulley-shaft for driving the lathe being also carried by said standards. The driving-gear consists of a spur-wheel mounted on the hollow carrier-shaft, hereinafter described, said spur-wheel being driven by a worm on the pulley-shaft, said pulley-shaft being at right angles to the axis of the lathe. The hollow carrier-shaft is constructed in two halves horizontally, which may be called the upper7 and lower halves, as the said shaft must always be in this position when the work is inserted or disengaged. The upper halfis hinged to the lower half, one half of the abovementioned spur wheel being permanently fixed to the latter. The other or loose half of the said spur-wheel is held in position by a couple of steel wedges and key-pieces. A cone-pulley is provided on the pulley-shaft for the different speeds.

In order that my invention may be better understood and more readily carried into effeot, I will now describe it with reference to the accompanying drawings, in Which- Figure l is a front view, partly in section, of my improved wheel-lathe, showing an axle and pair of wheels in position to be operated on. Fig. 2 is a plan of the same, also partly in section. Fig. 3 is a cross-sectional elevation on line A B of Figs. l and 2, showing the pulley-shaft and worm-gear for driving the spur-wheel. Fig. 4 is a part plan of the hollow carrier shaft, showing one of its end hinges; and Fig. 5 is an end elevation of same. Fig. 6 is a side elevation of the spurwheel on the hollow carrier-shaft, the lower part of said wheel being, as before mention ed, rigidly fastened to the carrier-shaft, Fig. 7 is an edge View of the spur-wheel on the hollow carrier-shaft, the upper portion of the ligure being in section.

The same letters refer to the same parts in the several iigures of the drawings.

a. is the bed-plate, preferably of cast-iron, having two ordinary fixed center head-stocks b b.

c c are the two A-shaped standards, provided with the hinged bearing-caps d d'.

e is the hollow split carrier-shaft, the upper portion e being hinged at f, Fig. 2.

g is the divided spur-wheel, the lower portion g of which is keyed to the lower half of the hollow carrier-shaft e, the upper half of said spur-wheel being connect-ed to the lower and held in position by wedges 7L and keys h', Figs. 2, 6, and 7.

j, Figs. 2 and 3, is the pulley-shaft, and j the worm-screw on same for driving the lathe.

7e 7c are the bearings of the pulley-shaft, supported by the A-shaped standards c c.

Z', Fig. 3, is the cone-pulley.

'm m' are the ordinary compound slide-rests for the operating-tools.

The upper and lower portions of the hollow carrier-shaft e are held firmly together by bolts n, Figs. l and 5, bolts or set-screws n being also provided for holding the axle and wheels to be operated upon firmly in the carrier-shaft.

The operation of my invention is as follows: Assuming it is desired to remove the work (axle and wheels) from the lathe, the hxed half of the spur-wheel being in the lower position, the key-pieces h, Fig. (i, are knocked out, and the upper half of the spur-wheel is then removed. The bolts o, which secure the loose end of the standard-bearing caps d d', are slackened andthe caps thrown back `on their hinges. The bolts n are also removed from the flanges on the vupper and lower halves of the ,hollow carrier-shaft e, the up- IOO per portion c of which is then thrown back on its hinges f, thus enabling the Work to be removed from the lathe. Fresh Work can now Abe inserted in the hollow carrier-shaft, the

formed in halves and provided with means for securing its halves together and to the axle, a Worm-Wheel also formed in halves and provided with means for securing its halves together and to the said carrier, a drivingshaft journaled under the Worm-Wheel cross- Wise of the carrier and provided With means for revolving it, and a .Worm secured on the said shaft and gearing into the said Worm- Wheel, substantially as set forth.
